Is it possible to have negative outputs?

Is it possible to have negative outputs?

All Answers (6) Yes, Negative values for the inputs & outputs can be used in DEA only thing is you have to first convert them to positive by adding a common number which can make all negatives to positives.

Is there such a thing as a negative result in research?

Unfortunately, while many clinical trials are eventually published, negative results (where the treatment being tested had no effect) are statistically less likely to be published. And negative trials results that are published come out about one year later than positive studies.

What is negative result in research?

There are three important reasons why researchers often get negative or null results. The original hypothesis was inaccurate and based on false and incorrect assumptions. Technical errors may include choosing a misfit study design, use of faulty reagents, or the use of inappropriate statistical methods.

How the negative results of the research can be presented in a research paper?

Explicitly explain why your negative results are essential to advancing knowledge in your field. Don’t rely on the reader to figure this out. For example, we wrote that the lack of an experimental effect in our study was informative because “it contrasts with a growing body of experimental work”.

What are negative outputs?

A negative output gap occurs when actual output is less than what an economy could produce at full capacity. A negative gap means that there is spare capacity, or slack, in the economy due to weak demand.

Can an objective function value be negative?

A negative objective function is not a problem. Remember that the objective function is -2*ln(Likelihood). This is negative if the ln(Likelihood) is positive or when the Likelihood is greater than 1. There is no restriction in the likelihood that would restrict it to be less than 1.

What is a negative study?

The term negative study originates from the hypothesis testing statistics with P values and statistical significance. Thus, a study is called negative, if the results for its main outcome are not statistically significant. In contrast, a positive study has shown statistically significant results for its main outcome.

What is a negative finding?

Negative and likelihood findings are findings with some uncertainty attached. Negative: A positive finding is knowledge that some variable definitely has a particular value. However, you may know that the value of a node is not some state without knowing what its value is. This is called a negative finding.

Is a negative expression?

A negative is a word, expression, or gesture that means ‘no’ or ‘not’. In the past we have heard only negatives when it came to following a healthy diet. In grammar, a negative clause contains a word such as ‘not’, ‘ never’, or ‘no-one’.

How do you present negative results in a positive way?

5 Simple Ways to Write about Negative Issues with a Positive Spin

1. 1 Present solutions instead of problems. It’s better to talk about what you can do rather than what you can’t.
2. 2 State what you want, not what you don’t.
3. 3 Keep hyperbole in check.
4. 4 Try “I statements.”
5. 5 “I’m sorry, but . . .” means you’re not sorry.

Why is it important to report non or negative events?

Reporting negative results also prevents other scientists from making the same mistake. Moreover, it saves time and efforts. For instance, once a researcher spent six months trying to synthesize an analog of a compound reported in the literature.

What is negative input?

A negative-input buck, just like its positive-input counterpart, has an input that is always larger in magnitude than the output. Simplified schematics for both of these topologies are shown in Fig. 2. While the same power components are used, only their locations relative to ground are changed.

Is it waste of resources to publish negative results?

Many scientists develop the attitude that following up on and publishing negative results is a waste of resources. Certainly, there is some truth in this statement because the costs may be high compared to the final output parameters (such as impact factor of the journal, citations etc.) reached at the end.

How to publish negative results in scientific review?

Make negative findings known in reviews (which can be published with a high impact factor) and in scientific talks. Push your institution, your scientific society and/or your funders to provide a public repository for negative results and to make it easy to make negative results publicly available without the hassle of a full publication.

Why are negative results published in the press?

NEGATIVE RESULTS ARE OFTEN PUBLISHED WITH A LOW IMPACT FACTOR BECAUSE EDITORS HATE BORING DATA. Editors want the exciting stuff: new mechanisms, unexpected findings and dramatic effects (“the paralyzed could walk again”) which increase citations, clicks, shares and press coverage.

When is a negative study considered less prestigious?

Consistently, negative studies are considered less prestigious if and when they do come out. High impact journals may be interested in negative studies when they destroy a long-held paradigm or when a new method is used to show that most previous studies are flawed.
